Cimarron River
The Cimarron dips into the very northwestern corner of the panhandle of
Oklahoma, goes into Colorado and Kansas and reenters Oklahoma in Beaver County,
exits the state again in Harper County and reenters the state again from Kansas as the
border between Harper and Woods Counties. It then meanders south and eastward across
the state and joins the Arkansas River at what is now Keystone Lake. It tends to be a
shallow, sandy river with shifting channels and sandbars similar in character to the
Arkansas, North Canadian and Canadian Rivers. Consequently, its mussel fauna is
limited to rather mobile species capable of dealing with such conditions.

North Canadian River
This river passes through most of the Oklahoma Panhandle as the Beaver River
and enters the main body of the state to become the North Canadian River. Hence it
flows south and eastward, parallel to the Cimarron River and joins the Canadian River at
what is now Lake Eufaula. This is another sandy, shifting prairie river similar to the
Cimarron and Canadian Rivers.
